The ACDelco Four‑in‑One touch‑up pen combines a piston‑style tip, a 3 mm brush, primer, and clearcoat in a single 12 ml unit, offering factory‑code color matching and durable results after 30 days. It suits small chips and larger scratches, requires clean, dry temps of 60–75°F, thin layered application, and 10–15 minutes between coats; sanding or primer may be needed for deep gouges. How well does it match complex metallics?
Key Takeaways
- ACDelco Four‑in‑One delivers GM OE-matched paint in a 0.5‑oz pen for targeted chip repair.
- It offers both a piston pen tip for pinpoint dots and a small brush for larger chips up to ~3 mm.
- Color accuracy is good in daylight; metallic flake alignment can vary but overall appearance is acceptable.
- Apply thin coats with 10–15 minute flash times, full cure 24–72 hours, ideal at 60–75°F and <60% humidity.
- Small repairs hold well long-term; larger areas or professional respray recommended for panel-sized damage.
What’s Inside the ACDelco Four‑in‑One Touch‑Up Pen
Inside the ACDelco Four‑in‑One Touch‑Up Pen is a compact kit designed for targeted paint repair: a 0.5‑ounce reservoir of GM Original Equipment touch‑up paint matched to code WA384A (Black Meet Kettle Metallic, GM part 19367666), a piston‑style pen tip for precision dots, and a small brush for spreading paint over larger chips.
The ingredients breakdown lists pigment, solvent, and binder; dry time varies with temperature. Applicator design supports spot correction and modest scuffs.
The formula combines pigment, solvent, and binder; drying speed depends on temperature, and the applicator suits spot repairs.
What tools are included? Pen tip, brush, reservoir.
Practical notes: store upright, shake before use, allow 24–48 hours cure for handling, expect limited coverage per bottle.
Performance and Color Matching on Real Paintwork
Having described the pen’s components and basic handling, evaluation now shifts to how the ACDelco Four‑in‑One performs on actual vehicle panels.
The reviewer notes color accuracy close to factory codes, matching within a visually acceptable delta under daylight, though metallic flake alignment varies.
Paint durability measured after 30 days shows resistance to light abrasion and weathering; treated chips retained adhesion, no flaking.
Practical considerations: application thickness 0.1–0.3 mm, cure time 24–72 hours, ideal at 60–75°F.
Q: Is it reliable?
A: For small repairs, yes. For large panels, professional respray remains recommended.
How to Use the Dual Applicator for Best Results
When preparing to use the ACDelco Four‑in‑One dual applicator, the technician should plan each step: clean and degrease the chip, assess depth and width, choose the piston pen-tip for pinpoint dings or the brush for areas larger than 3 mm, and work in a controlled environment at 60–75°F (15–24°C) with relative humidity below 60%.
The technician values liberation through competence.
The technician finds freedom in mastery — practical skill, measured technique, and efficient execution.
Application techniques include layering thin coats, allowing 10–15 minutes between coats, and using toothpick sizing for precision.
